Instructions

Step 1: Prepare the Brownie Batter

Preheat your oven to 325°F (163°C). Grease and line an 8×8-inch baking pan with parchment paper.
In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth.
Add the eggs and vanilla extract, mixing until fully incorporated.
Sift in the flour, cocoa powder, and salt, then stir until just combined (avoid overmixing for a chewy texture).
Pour the batter into the prepared pan and smooth the top.

Step 2: Bake the Brownies

Bake for 25-30 minutes, or until the edges are set and the center is slightly soft.
Let the brownies cool completely before adding the frosting.

Step 3: Make the Chocolate Frosting

In a small saucepan, heat the heavy cream over medium heat until it begins to simmer.
Remove from heat and add the chocolate chips, butter, and vanilla extract. Stir until smooth and glossy.
Let the frosting cool slightly before pouring over the brownies.

Step 4: Add the Signature Cosmic Sprinkles

Pour the warm chocolate frosting over the cooled brownies, spreading evenly.
Immediately sprinkle mini candy-coated chocolates on top.
Let the brownies sit at room temperature until the frosting sets.

Step 5: Slice and Enjoy

Once the frosting is firm, cut the brownies into 8-12 squares and serve!
